Important Uses
Cadmium is very useful for this society even today. As listed above, Cadmium hydroxide is used for nickel cadmium batteries, which are mostly used in railroad and aircraft industries for high power applications. Also, Cadmium sulphide and Cadmium sulphoselenide are used for pigments to show from bright yellow to deep red in plastics, ceramics, and glasses. Another useful compound of Cadmium would be Cadmium telluride and Cadmium sulphide. They are used in solar cells, and other semiconducting cadmium compounds in a variety of electronic applications.
